SCSI trouble on a MicroVAX IIGPX

I was recently rummaging through a MicroVAX II GPX, and found the card cage, as well as the convenient HD trays. I proceeded, out of curiosity, to remove the RZ55 and what seemed like a SCSI card as well as some other card mounted above the aforementioned card, connected to the tape drive. After a while, I decided to plug it all in again, but the VAX didn't seem to agree with my engineering principles. When I had chosen language, I reached the PROM prompt. It seemed to take a long time at the "6..." before the prompt, though. I know nothing about the VAX prompt, but I know that "b" or "boot" has caused it to boot before, so I did thus: 2... ?4F SCBINT, XQA0 ?06 HLT INST PC=00000EE6 Fel. What could have caused this? Have I inserted the QBUS card incorrectly? Or does the SCSI (Is it SCSI at all?) cable have t0o be inserted in any particular way into the drive? This is rather alarming, I don't wish to have inadvertently destroyed a fine VAX. =/ -- En ligne avec Thor 2.6. Vi m?ste vara r?dda om varandra - det ?r v?rt enda reciproka pronomen.
